I was installing a trigger guard and did some damage to it I got aluminum black to fix the color but I made a dimple from a punch when installing it any ideas on how this can get fixed

Not sure exactly where your damage has been done at without a pic. Look up Stark grip see if that would work in covering the damage . They work great if you break a ear off while inserting the roll pin . Here is a link of what i am talking about .
